AI Technical Summary
Shadows caused by the configuration and positioning of head-mounted devices (HMDs) interfere with accurate eye-tracking by reducing contrast and brightness differences between the pupil and surrounding eye regions, particularly when shadows appear in the pupil area.
A method and device for detecting shadows in the eye region of a user wearing an HMD by determining brightness levels in specific subareas of the eye region, comparing these levels to a predetermined threshold, and generating a signal to indicate the presence of a shadow, thereby improving eye-tracking accuracy.
Enhances the quality and accuracy of eye-tracking by effectively identifying and mitigating the impact of shadows, allowing for precise pupil detection and reducing errors in eye movement analysis.
